3. Nuclear reactions occur when the nuclei of two
different atoms collide to produce products
with different properties from the starting
substances. How is this similar to a chemical
change?
A. In a chemical change, mass can be created.
B. In a chemical change, energy can be created.
C. In a chemical change, mass can be destroyed.
D. In a chemical change, a new substance forms.
